Upstage Solar Decide: decision model from an established lab, built on Solar Mini 4
Upstage released Solar Decide in beta on its console (September 22, listed on OpenRouter September 28): a decision model built on Solar Mini 4 with a 512K context window and the same request format as TypeSafe Jev, at $0.05 per million input tokens via the route.
Why it matters
A decision-class model from an established model maker rather than a startup: the 512K context can take a whole document as the judgment state, and the Jev-compatible request format lowers the switching cost.
What you could build with it
A platform team could gate agent actions - tool routing, approvals, escalations - through Solar Decide at scale, using its 512K window to judge with the full document in context.
Does it hold up?
Too early to judge: beta, no independent evaluations published yet; the Jev-compatible request format means teams can A/B it against Jev cheaply.
